Cyber security is a serious challenge today as attackers specifically target web application vulnerabilities. This seminar is an introduction to application security threats, demonstrating the security problems that exist in the corporate systems with a strong emphasis on application security and secure design. During this seminar we cover the major security vulnerabilities including the OWASP top 10 vulnerabilities, and secure-design & coding best practices when designing and developing web applications & server based services.


This seminar main objective is:

  • raising the awareness on the problems that might occur without secure coding practices.
  • teach your important role in the corporate effort to secure its systems, while utilizing information security best practices.
  • to learn about the threat landscape and the controls you should use during the software development lifecycle.
